Detailed Description

template<typename Manifest, typename Resource, bool(*)(Resource &, const std::string &) loadFunction = &fileLoader>
class ml::ResourceManager< Manifest, Resource, loadFunction >

Generic manifest-driven resource cache.

ResourceManager<Manifest, Resource, loadFunction> is the base for all Malena asset managers. It maps enum keys (declared in Manifest) to loaded Resource instances, loading each resource lazily on first access and caching it for subsequent calls.

The load function is a compile-time parameter, allowing each resource type to use the appropriate SFML loading API without virtual dispatch.

Template Parameters

Manifest	A Manifest subclass whose enum keys map to file paths.
Resource	The SFML resource type to load and cache.
loadFunction	Function pointer bool(Resource&, const std::string&).

Member Function Documentation

get()

template<typename Manifest, typename Resource, bool(*)(Resource &, const std::string &) loadFunction = &fileLoader>

template<typename Asset>

const Resource & ml::ResourceManager< Manifest, Resource, loadFunction >::get ( const Asset & asset )

static

Retrieve the cached resource for an asset enum value.

Loads and caches on first access. Throws std::runtime_error if the path is not registered or loading fails.

Template Parameters

Asset

An enum type declared inside Manifest.

Parameters

asset

The specific enum value to load.

Returns

Const reference to the cached Resource.

unload()

template<typename Manifest, typename Resource, bool(*)(Resource &, const std::string &) loadFunction = &fileLoader>

template<typename Asset>

void ml::ResourceManager< Manifest, Resource, loadFunction >::unload ( Asset asset )

static

Remove a resource from the cache.

The next get(asset) call will reload from disk. If called during draw(), the unload is deferred until after the frame completes to prevent mid-frame dangling references.

Template Parameters

Asset

The enum type of the key to remove.

Parameters

asset

The specific enum value to evict from the cache.
